The Adaptec Series 7Q SAS / SATA RAID adapters, with maxCache 3.0, deliver evolved application acceleration benefits with the industry-first read caching solution and support for fully redundant SSD write caching. Adaptec's 71605Q and 7805Q adapters can deliver up to 25x improvement in IOPS and 25x reduction in latency compared to HDD-only storage arrays.
Adaptec maxCache 3.0 - The Evolution of Performance
Adaptec maxCache 1.0 offered significant performance gains for read-intensive applications. By using SSDs to cache copies of frequently accessed (aka "hot") data, maxCache exploits the performance capabilities of SSDs to store/access read data from them rather than spinning media. The read caching function is further improved with maxCache 3.0, with additional optimizations to the learned-path algorithm.
Advancing the performance capabilities of SSD caching to a broader set of application workloads, maxCache 3.0 has evolved to support write caching. By caching writes to a redundant SSD cache pool (either RAID1E or RAID5), maxCache 3.0 leverages the performance and latency capabilities of SSD technology for both read and write workloads.
Also new to maxCache 3.0 is the inclusion of the Optimized Disk Utilization (ODU) feature. As SSD sizes continue to increase, monopolizing their entire capacity as a cache-pool is becoming less attractive. ODU allows the SSD to be partitioned into both a cache pool and logical device. The logical partition, unlike the cache pool, is exposed to the operating system, and can be used to install an OS to it or store other data that requires fast, low-latency access.
Integration of maxCache 3.0 SSD caching technology is seamless. Adaptec Series 7Q adapters do not require changes to storage architectures, application software or operating systems.
